Abstract : Variations in the total muscle cholesterol content of Heteropnuestes fossilis followed a well defined seasonal cycle. The cholesterol content of the muscle was higher from September to January but declined rapidly from February onwards till the minimum value was obtained in April. Thereafter, a gradual increase was characteristic of the muscle cholesterol cycle. Both sexes showed similar patterns of seasonal variations. Although no direct relationship could be established between muscle cholesterol cycle and feeding, it was observed that muscle cholesterol values of H. fossilis declined with the advancement in maturation, reaching the lowest at peak ripeness. Higher muscle cholesterol values characterized the spent and recovering spent stages.
